Well......

Less than an hour ago I won an auction for a used Hensley hitch for my half ton Chevy that I have used to tow my 72 Sovereign on the ball for the last 10,000 miles or so.

I will update this thread when I see what kind of difference it makes.

Airstreams tend to have very heavy hitch weights. Both my '74 Argosy 20 and my '14 FC 20 have actual hitch weights right at 700 # loaded up and ready to go, and measured at scales. The only way to really know the tongue weight on your specific rig is to weigh it directly.

russellsue, your Airstream is light but you have to assume the hitch weight will be more than 420#. And anything you put in the bed of the truck behind the rear axle must also be added when trying to know what size w.d hitch you might need. 750# w.d bars would probably take care of it with some headroom, larger fine if they are the style that taper in size toward the rear. Your present friction sway bar seems to be working well.

Considering the relative size of your truck and Airstream using measurements to adjust your weight distribution, rather than scale weights is good enough.

Measure the empty truck fender wells of the front and rear before you hitch the Airstream and write them down. Then with the truck and Airstream loaded for camping and the Airstream hitched up, adjust the weight distribution so the fender well height drops equally, front and rear. Check that your Airstream is very close to level front to rear; if not adjust (or change) the receiver drop bar until it is. Then check your fender well measurements again.

This is a basic, simple method and "old hat" to the experienced. It ought to work for you and give you a safer and at least a little better handling rig.

I have the Andersen hitch. I have 20,000 miles experience towing. F150 Ecoboost and 30 foot Airstream. I have never been to the scales. I have been in big crosswinds, I have been on bad roads, trucks have blown passed me, crossed the divide many times. My rig feels stable, in control, not a problem. Safe.

Thanks for the technical information, I respect it, I read it. But I like to trust what seems to work, and enjoy the ride, and try to be happy, don't worry....
I have a friend who uses his F150 Ecoboost to tow his Airstream without any weight distribution or sway control and his description of towing is similar to ours. Take it to the scales and you will see the Andersen does not have the leverage to restore the front axle weight with your rig. Most believe there is a risk in that lack of capability and it may not be evident under normal towing conditions. The hitch is also incompatible with your Airstream coupler, a risk of breaking the coupler and disengaging. I sent mine back to the retailer and bought a hitch with 1400# conventional w.d. bars which performs better in every way.

Keeping with this thread, weight distribution to restore the truck's front axle weight is an important part of a safe towing combination.

I think weight distribution can help prevent sway buy keeping the front wheels on the ground, giving steering and braking control and resistance to side-to-side motion-

Yes, it's difficult for people without experience with a properly setup weight distribution system to understand that it is about much more than just redistributing the static load. As M.hony says, it will help with stability by redistributing the load of the tongue weight to both axles of the tow vehicle, making the tow vehicle drive better, and more stable, and thus the trailer is more stable. And it is about the transient loads applied to the hitch when driving over uneven pavement, and hitting bumps in the road.

It's not this simple, but I like to think of it as moving the tongue weight, by the use of a lever, from the hitch ball to just forward of the rear axle of the tow vehicle.

This can only be a good thing even if you tow a 16 footer with a Kenworth.

Not so, a big truck will stop faster and better fully loaded than with no trailer.

Even when talking about a pickup pulling a trailer the weak link can and often is that the rear axle of a TV can be too light to get good traction.

The Kenworth literally would not know the 16' trailer was there-
The dual rear wheels are the anti-sway and the 80,000# payload is the weight distribution, but-
A 1/2 ton Toyota pulling a 30' Airstream knows it's there-
As a 250 or 350 would still know it's there-
a 350 dual rear wheel on the other hand-

18 wheeler tractors are designed to stop better/have better traction with a load.
An 18 wheeler tractor with no trailer is much less stable.
My Toyota- not so much-

Guess my attempts at exaggeration humor are just too dry for you guys.

I git it-
Just sayin'-
Your example of a lever is exactly how it is-
Weight distribution hitches also keep your headlights from blinding other drivers-

Please humor my fantasy that I understand 19th century physics. I know for certain that I don't grok 20th century physics.

My underlying assumption for what follows is that control derives from the coefficient of friction that the tires and road have. Nothing else. If you had Tour de France bike wheels and tires strong enough to support your TV then your control derives from the coefficient of friction. The same would be true for monster truck wheels and tires. Neither would be practical, but for e.g. one straight line stop if the coefficient of friction is the same the stop will be the same.

Fat, skinny, road tread, snow tread,,, will have different coefficients of friction on dirt,asphalt, concrete,,, roads. For the discussion of WD that is irrelevant.

With a too-high tongue weight the front end is lightened, the coefficient of friction (CofF) is diminished and the possibility of loss of control goes up. As has been pointed out, pickup trucks may be light in the rear, hence diminished CofF too.

Perhaps it is a rarity in our language, but WD is exactly what it says it is. We need a proper distribution in our vehicles and TVs. Sometimes we need nothing to achieve that distribution, sometimes we need massive trunnions, or any shade of gray in between.

With pickup trucks which are designed to tow the manufacturers provide guidance. For example my F-250 requires WD if the tongue weight is >600 lbs. I suspect that in an accident, had I ignored that it could constitute at least partial negligence. Perhaps auto and SUV manufacturers do a good job too but I don't know.

I hope I haven't made things worse. And, if we have any real physicists out there, please keep me honest!
